I thought the pacing was good. It's a full two hour movie, which is longer than I typically prefer, but I didn't even notice and was engaged for the whole duration. It's not the type of drama that takes a long time to set things up. It actually jumps around chronologically, almost flashback-style.

Great film, indeed. Loved it too.

Saw it several years ago and just rewatched it a month or so ago. GREAT film with good performances by all...kind of eerie that Philip Seymour Hoffman plays a clandestine heroin user in here , seeing H is what killed him.
Also Marisa Tomei is gorgeous....
